Delx Cron Next Fires
x402
Delx Cron Next Fires is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Computes the next N fire timestamps for a cron expression starting from a given Unix timestamp

How this service works
Next N hourly fires from a simple '0 * * * *' style hour cron. Call when scheduling previews for basic hourly/daily crons. Returns next_fire_unix list as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing the original cron expression, a schema identifier, and an array of Unix timestamps representing the next N scheduled fire times in chronological order.
Example use cases
Preview hourly job schedule
“I want to see the next 3 times my hourly cron job '0 * * * *' will fire, starting from Unix timestamp 1700000000 — can you calculate those for me?”
Agent scheduling next workflow trigger
“My automation runs on '30 9 * * *' and I need to know the next 10 scheduled fire times starting from timestamp 1699900000 so I can plan dependent tasks.”
Validate cron expression timing
“Can you show me the next 4 execution times for the cron expression '0 6 * * *' starting from timestamp 1700050000 so I can confirm the schedule looks right?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/cron-next-firesWhen to prefer
Use this endpoint when an agent needs to deterministically compute future cron fire times without running a scheduler — ideal for previewing, validating, or planning around scheduled jobs. Prefer over general-purpose scheduling APIs when you only need pure timestamp computation with no side effects and you are operating within the hourly-subset cron syntax this service supports.
Side effects
- Invalid cron expression returns an error or empty result
- Cron expression outside the supported hourly subset may fail or produce unexpected results
- Missing required fields (expr or from_ts) may cause a validation error
- Very large values of n may result in slow responses or payload limits
- Malformed Unix timestamp may produce an error or incorrect schedule
